1 piece rear seal. The heads are similiar for intake ports as most other big ovals, with the exception of a swirl bump, next to the guide. The Exhaust port is a smaller D-port deal, with more short turn meat. The chamber is slightly better. As fas as the engine fitting, it will no issue. Like was said though, no provision for a mechanical fuel pump, which isn;t the end of the world. Otherwise, its a great street engine. With a bit of work to the heads, and a cam and intake, they make killer power
